CARBURETER.

Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed March 16, 1905. Serial No. 250,467.

To a/ZZ whom it may concern:

Beit known that I, ADOLPHE CLMENT, a citizen of the, Republic of France, residing in Levallois-Perret, Seine, France, have in vented certain new and useful 11n rovements in Carbureters, of which the following is a specification. 4This invention has for its object a carbureter specially adapted for motors which are governed on the admission, its pur ose being to give the maximum explosive orce under whatever regimen the motor may be running. This carbureter, which is represented in vertical section in Figure 1 and in plan in-Figl 2, consists of a constant-level reservoir A, distributing the s irit to the injector B of a carbureter-bo y C, provided with a throttle-valve a and provided at its lower part with a conicalA nozzle b, in the axis of which, the injector is situated. At the lower part ofthe carbureter-body C is placed a cup D, which communicates with the atmosphere through a conduit c, throu h which the air reaches the nozzle b around t e injector B.

An additional air ladmission beyond the nozzle b is effected through the conduit E, which communicates with the tubular box F, in which are arranged two valves G and H, which re ulate the additional air-supply. These va ves G and H are oppositely arranged and opposed and are displacement y an assemb age of small levers cl e f which connect the spindles g h outside the tube F. A spiral spring K is connected by one extremity with the arm llc, mounted upon the spindle g, and by the other extremity with the screw-threaded rod 1, thus'permitting of the regulation of the force with which the valves are applied to their seats.

4The operation is as follows: On starting the motor and at low speeds-that is to say, when the reduction of pressure or degree of vacuum is very small-the air enters only through the orifice D and passes around the injector B inside'the conical nozzle 2'), the small section of which imparts to it suiiicient velocity for efectingpulverization under good conditions, and conse uently obtaining etlicient carburation. Iii t e admission of the motor is increased, the reduction of pressure increases and tends to cause the opening ofthe valves G and H, acting upon the upper valve G, owing to the communication. aiM fcrded by the oriiice o of the valve H. The

supplement ary air reaches Ein the carbureter. g

Owing to the conical nozzles, the vacuum increases around the injector B.

By judiciously selecting the sections of the various conical nozzles and the spring K of the opposed valves a constant carburation under all conditions is obtained.

,In a carbureter, in combination, a con* stant-level reservoir, a carbureter-body C having a conical lower end, a throttle-valve, a conical nozzle b e tering said lower end of the body C, an injector B in the axis of said nozzle and connected with the reservoir, and a chamber D surrounding said injector B and `communicating with the atmosphere and with the interior ofthe nozzle b.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
